The rapid changes of information technology led to the proliferation of Web-based Information Systems (WIS). There has been already some research on the general model for analysis and design of WIS. This paper attempts to define a comprehensive framework for integrating the various viewpoints of model for WIS. Several components that compose of a WIS as analyzing and designing element are investigated and described as modeling element and enabling tool for creating consistent and integrated system. The major modeling components are: the Web site, semi structured document, business processes, element of knowledge management, the enterprise and information architecture, and autonomous software components providing functional services. These elements are integrated into a unified framework exploiting partly the object-oriented paradigm and partly other approaches for information system modeling. The outlined WIS model incorporates the most recent approaches for various paradigms of traditional information systems analysis and the most modern different approaches of WIS. The research result would be useful both theoretically and practically as it could present a comprehensive model for WIS assisting our understanding of properties of WIS and supporting, at the same time, a framework for being able to formulate a practical development method for achievement of WIS by organizations making the most of Web.
Abstract:Web Information Systems (WIS) are becoming more and more ubiquitous along with the changes in information technology. There have already been several studies on modeling various aspects of WIS. This paper attempts to investigate the most recent paradigms of WIS description taking into account the Web service approaches, Service Oriented Architecture and Cloud computing. One of the modeling and analysis approaches is the Artifact Centric Business Process that unifies both the behavioural and information aspects of business processes carried out in a WIS environment. The information aspect frequently incorporates in the form of unstructured or semi-structured document that indirectly influences the content of the underlying database through several tiers of the given architecture. A business event stimulates a business process along with some set of data and triggers a process at the user interface level. The process initiates a chain of processes that goes through the tiers of architecture until the content of the database is affected. The Story Algebra, or more generally the Process Algebra approach provides a formal framework that promises a formal describing method for modeling precisely the event triggered processes coupled with data in document format.
We live in an era of big data. Large volumes of complex and difficult-to-analyze data exist in a variety of industries, including the financial sector. In this paper, we investigate the role of big data in enterprise and technology architectures for financial services. We followed a two-step qualitative process for this. First, using a qualitative literature review and desk research, we analyzed and present the data science tools and methods financial companies use; second, we used case studies to showcase the de facto standard enterprise architecture for financial companies and examined how the data lakes and data warehouses play a central role in a data-driven financial company. We additionally discuss the role of knowledge management and the customer in the implementation of such an enterprise architecture in a financial company. The emerging technological approaches offer opportunities for finance companies to plan and develop additional services as presented in this paper.
After the quick growth of the Internet users several things are changed, the simply users became authors of the content, several new web applications appeared and meanwhile few web companies became significant IT corporations. The new web services are based on a real business model. Today Microsoft is the largest IT company, Google shortly became one of the biggest media corporations mainly based on the search and advertisement market with the highest growth potential. In a few years, Google could be as big as Microsoft is now. Pending my presentation, I will demonstrate the SWOT analyzes of Google and the new web business model.
